ABSTRACT

La leucemia es una patología neoplásica maligna que constituye un problema de salud que afecta fundamentalmente a la población infantil. Así, se realizó un proceso investigativo con el objetivo de describir la calidad de vida en pacientes pediátricos de LLA con edades entre 2 y 18 años, atendidos en 2019, en el Hospital Pediátrico Baca Ortiz y en el Hospital de Solca - Núcleo Quito, Ecuador; para lo cual se hizo un estudio observacional, transversal, descriptivo, con enfoque cuantitativo. Los datos fueron recopilados mediante la revisión de las historias clínicas de los 60 pacientes en el contexto de investigación. El 66,7% correspondió al sexo masculino, el 43,3% tenía edades entre 2 y 4 años, el 38,3% tuvo fiebre como síntoma inicial. El síndrome de Down resultó la comorbilidad más frecuente (6,7%). En 54 pacientes se diagnosticó LLA tipo B. El 66,7% recibía terapia psicológica, 22 de los enfermos estaban en la fase de inducción y mantenimiento. El 65% abandonó la escuela mientras se le administraba quimioterapia. Predomina-ron los que consideraron su calidad de vida como buena, seguido de los que tuvieron severa afectación. Las mayores afectaciones en los participantes fueron: dificultades con la alimentación, presencia de dolor, falta de comunicación, existencia de ansiedad y presencia de estrés por la preocupación debido a la posible infectividad del tratamiento.


Leukemia is a malignant neoplastic disease that constitutes a health problem that mainly affects children. Thus, this research aimed to describe the quality of life in pediatric ALL patients between 2 and 18 years of age, treated in 2019, at the Baca Ortiz Pediatric Hospital and at the Solca Hospital - Núcleo Quito, Ecuador. A cross-sectional, descriptive, and observational study with a quantitative approach. Data were collected by reviewing the medical records of the 60 patients in the research context. 66.7% were male, 43.3% were between 2 and 4 years old, 38.3% had fever as the initial symptom. Down syndrome was the most frequent comorbidity (6.7%). Type B ALL was diagnosed in 54 patients. 66.7% received psychological therapy. 22 of the patients were in the induction and maintenance phase. 65% dropped out of school while recei-ving chemotherapy. Those ones who considered their quality of life as good predominated, followed by those ones who were severely affected. The greatest effects on the participants were: difficulties with feeding, presence of pain, lack of communication, existence of anxiety and presence of stress due to worry due to the possible infectivity of the treatment.

ABSTRACT

Introdução: Quando se fala em câncer infantojuvenil, a leucemia linfoide aguda (LLA) ganha destaque por causa da sua elevada prevalência nessa população. De todos os tipos de câncer que atingem esse público, crianças e adolescentes parecem ser mais suscetíveis aos efeitos adversos como a má nutrição e/ou excesso de peso ao longo do tratamento. Objetivo: Avaliar a evolução do estado nutricional de crianças e adolescentes com LLA submetidos à terapia oncológica. Método: Estudo retrospectivo, longitudinal, com pacientes portadores de LLA submetidos à terapia antineoplásica, realizado com 69 crianças e adolescentes (até 19 anos), de ambos os sexos. As medidas de peso e altura foram coletadas em oito ocasiões distintas ao longo de todo o tratamento, tendo o primeiro registro acontecido no início e o último ao término de todas as sessões do tratamento antineoplásico. Resultados: Ao diagnóstico, houve uma prevalência de pacientes classificados como eutróficos. Quando correlacionados a faixa etária e o indicador Altura/Idade para idade, foi observado que crianças menores de 10 anos apresentaram valores mais baixos se comparados com os maiores de 10 anos no decorrer do tratamento, além de uma tendência de incremento no escore Peso/Idade de forma lenta até o seu final. Conclusão: Os pacientes submetidos ao tratamento antineoplásico de LLA apresentaram uma redução na velocidade de crescimento, além de leve ganho de peso ao final da terapia, o que sugere uma interferência negativa da terapêutica empregada sobre o estado nutricional nessa população


Introduction: When it comes to childhood cancer, acute lymphoid leukemia (ALL) stands out due to its high prevalence in this population. Of all types of cancer affecting this population, children and adolescents seem to be more susceptible to adverse effects such as malnutrition and/or overweight during treatment. Objective: To evaluate the evolution of the nutritional status of children and adolescents with acute ALL undergoing cancer therapy. Method: Retrospective, longitudinal study with patients with ALL undergoing antineoplastic therapy carried out with 69 children and adolescents (up to 19 years old) of both sexes. Weight and height measurements were collected on eight different occasions throughout the treatment, the first at the beginning of the treatment and the last at the end of all the sessions of antineoplastic treatment. Results: At diagnosis, there was prevalence of patients classified as eutrophic. When the age group and the indicator of Height/Age for age were correlated, it was observed that children under 10 years old had lower values when compared to those older than 10 years during the treatment, in addition to a rising trend of the Weight/Age score slowly until its end. Conclusion: Patients undergoing antineoplastic treatment for ALL presented a reduction in the velocity of growth, in addition to a slight weight gain at the end of the therapy, which suggests a negative interference on the nutritional status of this population

Objetivo: Evaluar la evolución del estado nutricional de niños y adolescentes con LLA en tratamiento oncológico. Método: Estudio longitudinal retrospectivo con pacientes con LLA sometidos a tratamiento antineoplásico. Realizado con 69 niños y adolescentes (hasta 19 años), de ambos sexos. Las medidas de peso y talla se recogieron en ocho ocasiones diferentes a lo largo del tratamiento, donde el primer registro tuvo lugar al inicio del tratamiento y el último al final de todas las sesiones de tratamiento antineoplásico. Resultados: Al diagnóstico, hubo una prevalencia de pacientes clasificados como eutróficos. Cuando el grupo de edad y el indicador Altura/Edad se correlacionaron, se observó que los niños menores de 10 años presentaron valores menores en comparación con los mayores de 10 años durante el tratamiento, además de una tendencia a aumentar el Peso/Edad puntúe lentamente hasta el final. Conclusión: Los pacientes sometidos a tratamiento antineoplásico de LLA mostraron una reducción en la velocidad de crecimiento, además de un ligero aumento de peso al final de la terapia, lo que sugiere una interferencia negativa de la terapia utilizada sobre el estado nutricional de esta población

ABSTRACT

ABSTRACT Introduction: Flow cytometry has become an increasingly important tool in the clinical laboratory for the diagnosis and monitoring of many hematopoietic neoplasms. This method is ideal for immunophenotypic identification of cellular subpopulations in complex samples, such as bone marrow and peripheral blood. In general, 4-color panels appear to be adequate, depending on the assay. In acute leukemias (ALs), it is necessary identify and characterize the population of abnormal cells in order to recognize the compromised lineage and classify leukemia according to the WHO criteria. Although the use of eightto ten-color immunophenotyping panels is wellestablished, many laboratories do not have access to this technology. Objective and Method: In 2015, the Brazilian Group of Flow Cytometry (Grupo Brasileiro de Citometria de Fluxo, GBCFLUX) proposed antibody panels designed to allow the precise diagnosis and characterization of AL within available resources. As many Brazilian flow cytometry laboratories use four-color immunophenotyping, the GBCFLUX has updated that document, according to current leukemia knowledge and after a forum of discussion and validation of antibody panels. Results: Recommendations for morphological analysis of bone marrow smears and performing screening panel for lineage (s) identification of AL were maintained from the previous publication. The lineage-oriented proposed panels for B and T cell acute lymphoblastic leukemia (ALL) and for acute myeloid leukemia (AML) were constructed for an appropriate leukemia classification. Conclusion: Three levels of recommendations (i.e., mandatory, recommended, and optional) were established to enable an accurate diagnosis with some flexibility, considering local laboratory resources and patient-specific needs.

ABSTRACT

Introducción: El pronóstico de las enfermedades hematológicas malignas ha experimentado un importante avance en las últimas décadas, sobre todo por las nuevas combinaciones de quimioterapia. Estos hechos han propiciado que muchos de estos pacientes, en algún momento de su enfermedad, sean tratados en unidades de cuidados intensivos, lo que no era frecuente hace dos décadas. Objetivo: Describir el desarrollo de la disfunción múltiple de órganos en pacientes pediátricos con leucemia linfoide aguda en terapia intensiva en el Instituto de Hematología e Inmunología. Métodos: Se realizó un estudio clínico, observacional, transversal en el que se incluyeron los pacientes pediátricos con leucemia linfoblástica aguda y disfunción múltiple de órganos, atendidos en el servicio de terapia intensiva en el periodo 2018 a 2020. Se analizaron las variables: sociodemográficas, estado nutricional, diagnóstico al ingreso, puntaje del score pSOFA, conducta fármaco-terapéutica. Resultados: El grupo de edad más afectado fue el de 1 a 4 años, en su mayoría normopesos, con complicaciones de choque séptico, distrés respiratorio, y con 33 por ciento de mortalidad mayor en aquellos pacientes con score pSOFA con más de 10 puntos. La conducta terapéutica más utilizada fue la administración de oxígeno, fluidoterapia y antibióticos de tercera y cuarta generación en la primera hora de ingreso al servicio. Conclusiones: Si el puntaje del score pSOFA es mayor de 10 puntos existe mayor riesgo de muerte y mortalidad pediátrica (90 por ciento )(AU)


Introduction: The prognosis of hematological malignancies has undergone an important advance in the last decades, mainly due to the new chemotherapy combinations. These facts have led many of these patients to be treated in intensive care units at some point during their illness. Objective: To describe the development of multiple organ dysfunction in pediatric patients with acute lymphoid leukemia in intensive care at the Institute of Hematology and Immunology. Methods: A clinical, observational, cross-sectional study was carried out that included pediatric patients with acute lymphoblastic leukemia and multiple organ dysfunction, treated in the intensive care service in the period from 2018 to 2020. The variables were analyzed: sociodemographic, nutritional status, diagnosis on admission, pSOFA score, drug-therapeutic behavior. Results: The most affected age group was 1 to 4 years old, mostly normal weight, with complications of septic shock, respiratory distress, and 33 percent higher mortality in those patients with a pSOFA score with more than 10 points. The most used therapeutic approach was the administration of oxygen, fluid therapy and third and fourth generation antibiotics in the first hour of admission to the service. Conclusions: If the pSOFA score is greater than 10 points, there is a greater risk of death and pediatric mortality (90 percent)(AU).

ABSTRACT

Abstract Introduction: The minimal residual disease (MRD) status plays a crucial role in the treatment of acute lymphoblastic leukemia (ALL) and is currently used in most therapeutic protocols to guide the appropriate therapeutic decision. Therefore, it is imperative that laboratories offer accurate and reliable results through well standardized technical processes by establishing rigorous operating procedures. Method: Our goal is to propose a monoclonal antibody (MoAb) panel for MRD detection in ALL and provide recommendations intended for flow cytometry laboratories that work on 4-color flow cytometry platforms. Results and conclusion: The document includes pre-analytical and analytical procedures, quality control assurance, technical procedures, as well as the information that needs to be included in the reports for clinicians.

ABSTRACT

SUMMARY OBJECTIVE: Acute lymphoblastic leukemia (ALL) is the most common type of childhood cancer. Previous studies have indicated the involvement of vitamin D receptor (VDR) and related long noncoding RNAs (lncRNAs) signaling in the pathophysiology of several cancers. However, their contribution to ALL remains to be elucidated. METHODS: In this case-control study, 30 patients with newly diagnosed ALL and 30 age- and sex-matched healthy children were selected. Then, the level of 25(OH) vitamin D and the expression of VDR and four VDR-related lncRNAs were assessed. RESULTS: No significant difference in serum 25(OH) vitamin D was observed between patients with ALL (20.42±6.5 ng/mL) and healthy subjects (25.45±11 ng/mL). In addition, the expression of MALAT-1, HOTAIR, and P-21 was not statistically significant between the two groups. However, a significant reduction in VDR and H19 expression was observed in patients with ALL (p<0.05). CONCLUSIONS: 25(OH) vitamin D insufficiency was evident in both groups. VDR and H19 signaling might be contributed to the pathogenesis of ALL, which needs further investigations.

ABSTRACT

La leucemia linfoblástica aguda (LLA) es la patología oncológica más frecuente en pediatría, y corresponde al 23% de las neoplasias en menores de 15 años. Alrededor del 20% de los pacientes con LLA presentan recaídas, en la mayoría de los casos, en la médula ósea. Las recaídas extramedulares son inusuales y las dos localizaciones más frecuentes son el sistema nervioso central (SNC) y los testículos. Cuando las recaídas ocurren en el SNC, suelen manifestarse con un síndrome meníngeo. El síndrome hipotalámico se define como la presencia de hiperfagia, obesidad y/o cambios en el estado de ánimo, y es una forma de presentación clínica inusual de las recaídas en el SNC y debe alertar al pediatra para mantener un alto índice de sospecha.Se describen cuatro casos que se presentaron con síndrome hipotalámico al momento de desarrollar una recaída de LLA en el SNC


Acute lymphoblastic leukemia (ALL) is the most common malignancy in childhood, corresponding to 23% of cancer in children younger than 15 years old. About 20% of ALL cases will relapse, commonly in the bone marrow. Extramedullar relapses are unusual, and the two most frequent locations are CNS and testicles. ALL relapses, when diagnosed in the CNS, frequently present with clinical features of a meningeal syndrome. The hypothalamic syndrome, consisting of hyperphagia, obesity and / or behavior disturbances, corresponds to an unusual presentation of relapses in this location and should alert pediatricians to suspect it.We describe 4 ALL cases of hypothalamic syndrome at the time of CNS relapse

ABSTRACT

ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common malignancy in children characterized by the overproduction and accumulation of immature lymphoid cells in the bone marrow and peripheral blood. The BMI-1 is an important component of the Polycomb Repressive Complex-1 (PRC1). It is an important molecule for the self-renewal of hematopoietic stem cells (HSCs). The BMI-1 expression is generally high in HSCs and decreases after cell differentiation. The BMI-1 is required for the maintenance of normal and cancer stem cells and has been reported as an oncogene in various tumors. The NANOG is a homeodomain transcription factor responsible for maintaining the stem cell compartment at the blastocyst stage of developing embryos. The NANOG gene has been proven to be transcribed in CD34+ cells and different leukemic cells. Methods The ribonucleic acid (RNA) was extracted from the peripheral blood mononuclear cells (PBMNCs) of 30 pediatric ALL patients (16 B-ALL and 14 T-ALL) and 14 healthy controls. The Bmi-1 and NANOG expression levels were determined using the quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Results Compared to normal controls, patients with ALL exhibited upregulated levels of Bmi-1 (p = 0.03). Patients who overexpressed Bmi-1 and NANOG displayed a significantly worse survival than low-expressing patients (hazard ratio (HR) 5.74, 95% confidence interval (CI):1.48-22, p = 0.012 and HR 3.8, 95% CI:1.009-14.3, p = 0.048, respectively). Conclusions Taken together, these data suggest that the Bmi-1 and NANOG might serve as a novel survival predictor in ALL patients. Our observation also suggests that the Bmi-1 and NANOG could serve as new therapeutic targets for treatment of pediatric ALL.

ABSTRACT

Las leucemias son las neoplasias malignas más frecuentes en la infancia; la leucemia linfoblástica aguda (LLA) es la más frecuente. Desde principios de los 80, la adición de metotrexato intratecal a los esquemas de quimioterapia ha sido beneficiosa para prevenir la recidiva en el sistema nervioso central y evitar el uso de radioterapia. Su mecanismo de acción es la inhibición de la enzima dihidrofolato reductasa, por lo que posee múltiples efectos adversos (neurotoxicidad aguda, subaguda o crónica) después de la infusión intratecal o de dosis altas por vía intravenosa.Se presenta un paciente de 11 años con diagnóstico de LLA de línea T (LLA-T), que presenta hemiparesia faciobraquial y afasia de expresión de instauración aguda 8 días después de la administración intratecal de metotrexato. Luego de excluir otras patologías más frecuentes de origen vascular y la evolución típica del cuadro, con resolución espontánea ad integrum de los síntomas, se arribó al diagnóstico de encefalopatía subaguda reversible por metotrexato.


Leukemias are the most frequent malignant neoplasms in childhood; acute lymphoblastic leukemia (ALL) is the most frequent. The addition of intrathecal methotrexate to chemotherapy regimens has been beneficial in preventing relapse to the central nervous system and avoiding the use of radiation therapy. Due to its mechanism of action, by inhibiting the enzyme dihydrofolate reductase, when it is used systemically, it has multiple expected adverse effects such as mucositis, myelosuppression and it has also been observed after intrathecal administration or high intravenous doses, acute, subacute neurotoxicity where stroke like syndrome is found. We present an 11-year-old patient diagnosed with T-ALL, who manifested after 8 days of intrathecal administration of methotrexate, faciobrachial hemiparesis and acute onset expression aphasia. The diagnosis of subacute encephalopathy reversible by methotrexate was reached by excluding other more frequent pathologies and the typical evolution, with spontaneously ad integrum resolution of the symptoms

Introduction: Neurocutaneous syndromes comprise a heterogeneous set of hereditary disorders mainly affecting the skin and the central nervous system. Among the conditions included are neurofibromatosis, tuberous sclerosis and von Hippel-Lindau disease, characterized by dysplasia in various tissues and the formation of tumors in various organs. Increased relative risk has also been described for acute lymphoblastic leukemia, chronic myelomonocytic leukemia and non-Hodgkin lymphoma. Objective: Describe the case of a patient diagnosed with neurocutaneous syndrome (tuberous sclerosis) who developed acute lymphoid leukemia at age six. Clinical case: A case is presented of a female six-year-old patient with a history of neurocutaneous syndrome, tuberous sclerosis type, diagnosed at age two. The patient started with febrile syndrome, cervical adenopathies and hepatosplenomegaly. The blood count revealed anemia, severe thrombocytopenia and leukocytosis with the presence of blasts, whereas the medullogram showed 90 percent infiltration by lymphoid blasts, leading to the diagnosis of acute lymphoid leukemia. Conclusions: Coexistence of neurocutaneous syndromes and acute lymphoid leukemia is not frequent. A case is described of a patient with both conditions who died despite the treatment indicated(AU)

ABSTRACT

ABSTRACT Introduction: To assess the frequency of allergic reactions to asparaginase (ASP) and possible risk factors for reactions in a cohort of pediatric patients. Method: The study was performed based on retrospective data from patients under acute lymphoid leukemia treatment in a general university hospital located in southern Brazil. Information on patients who used ASP from 2010 to 2017 was collected. Allergic reactions were identified in electronic medical records. Results: Among the 98 patients included in the study, 16 (16.3 %) experienced an allergic reaction to native l-asparaginase (L-ASP). Of the 22 patients (22.4 %) that received only intravenous (IV) administration of l-ASP, 10 (62.5 %) had allergic reactions, while 48 patients (49 %) received intramuscular (IM) administration and 28 (28.6 %) received IV and IM administrations. The occurrence of allergic reactions differed between the groups (p < 0.001), and IV administration was associated with allergic reactions. Association was also observed between the severity of the reaction and the route of administration, with the IM route associated with grade 2 and IV route associated with grade 3. Occurrence of allergic reactions was higher when the commercial formulation of l-ASP, Leuginase®, was used (p = 0.0009 in the analysis per patient and p = 0.0003 in the analysis per administration). Conclusions: The IV administration and commercial Leuginase® presentation were associated with more allergic reactions in the study population, which corroborates the findings in the literature. The IV route was also associated with higher severity of reactions in the present study.

ABSTRACT

ABSTRACT Aberrant expression of long non-coding RNAs (lncRNAs) has been detected in several types of cancer, including acute lymphoblastic leukemia (ALL), but lncRNA mapped on transcribed ultraconserved regions (T-UCRs) are little explored. The T-UCRs uc.112, uc.122, uc.160 and uc.262 were evaluated by quantitative real-time PCR in bone marrow samples from children with T-ALL (n = 32) and common-ALL/pre-B ALL (n = 30). In pediatric ALL, higher expression levels of uc.112 were found in patients with T-ALL, compared to patients with B-ALL. T-cells did not differ significantly from B-cells regarding uc.112 expression in non-tumor precursors from public data. Additionally, among B-ALL patients, uc.112 was also found to be increased in patients with hyperdiploidy, compared to other karyotype results. The uc.122, uc.160, and uc.262 were not associated with biological or clinical features. These findings suggest a potential role of uc.112 in pediatric ALL and emphasize the need for further investigation of T-UCR in pediatric ALL.
